Regarding the production of the large dust masses found at high-redshift (REBELS and other ALMA observations find dust masses \(M_\mathrm {dust} \gtrsim 10^7\,M_\odot \)  at \(z\simeq 7\) ), models have not reached a consensus yet. Some models find that the dust masses can be explained by high supernova rates and/or yields, or efficient ISM dust growth (e.g., [1]}), while others find that efficient ISM growth is needed (e.g., [2]}). The need for efficient ISM dust growth in early galaxies may be problematic: [3]} point out that at high-redshifts, icy dust grain mantles formed in the cold ISM do not survive in the hot diffuse ISM. Recently, [4]} showed that the DELPHI semi-analytic model can reproduce the dust masses of REBELS sources with minimal ISM dust growth, coupling metal and dust enrichment, and using new stellar yields from [5]}.
